I'm up to reinstall Arch on my laptop while I have a bit of a time and I've encountered an interesting question to ask.
Is there any way to check my laptop battery status without installing acpi package? (as I'm currently offline without charger and I can't get neither of them)
I thought that system should keep track of a battery level somehow. So is it possible to display that info in CLI?

Have a look at the files in/sys/class/power_supply/. May or may not work for your particular hardware.

The kernel provides this information through /sys/class/power_supply/BAT0/capacity
Simply cat this path to get the information (in percent of your batteries capacity):
cat /sys/class/power_supply/BAT0/capacity
For an live view you can combine cat with the command watch. The following command provides you a an, updated, live status of your batteries capacity:
watch -n0 cat /sys/class/power_supply/BAT0/capacity
If your system has more then one battery, BAT0 under /sys/class/power_supply/ may be BAT1, BAT2 or something different. Look at the devices under ls /sys/class/power_supply/ and cat their information.
